VTS trim moves only in one direction

Ok guys.. got the vts motor out, and tested it on a battery...turns out, the motor does work..in both directions..
Now i see what you guys mean about the worm screw...but it seemed like something wasn't right with it..like if i screwed it all the way in, it would go down, then i would unscrew it, it would come up, then i could just kinda push the worm screw housing in, NOT turning it, just pushing it, then if i would unscrew it again it would go down, instead of up...
something just didnt seem right...
anyway, the motor works, so i just took a spare set of vts handlebar buttons off my other hull, and I'll try replacing them first as its a quick fix...but i'm leaning more on the fact that the module in the back of the housing is bad..what do you guys think?
also, since now that i feel like i've kinda messed with it, does anyone know where the stock/factory setting is, so if/when i get it working, it will be set right?
meaning like does anyone know how many turns out from all the way in does the worm screw have to be set? and also, the adjustment screw/nut on the outside of the hull, where that is supposed to be set for stock?
thanks guys

Ok... lots of questions lol. Glad the motor is working, and from my research they usually do, it's the module. But before you mess with the vts button, what I would do is hook the motor up back to it's normal wiring, NOT in it's housing tho, just loose so it won't be turning the worm screw, then try the vts button and see if it moves the motor. If it does, then your module and button are fine, your worm screw is stuck. That will be the quickest and cheapest test. Do this first!!!!

I don't really understand what you are trying to describe. The worm screw is pretty basic concept. I'm guessing you are pushing it in and out with the motor out? Have you taken the worm screw right out? Take it out and look at it. There really isn't much to it. It shouldn't be able to be pushed in or out when the motor is installed.

When I put my bros back together and tested it, the gauge detected where it was at, so I didn't have to adjust anything i.e. screw the worm screw all the way in, set the gauge at high trim position. When I took his apart it was all the way down, put it back together and it read correctly at about half way.
The back rod outside the hull, you should have touched the lock nut on the rod, that is set correctly, you only needed to take off the one screw that makes it move up and down on the very back outlet that also turns with the handle bar (sorry can't think of the name).

Try the first thing I mentioned and go from there. GL!
 
ok great, i will try the first thing soon..
what i meant when i was trying to describe that something wasn't right...was that i could screw the worm screw all the way up and all the way down..but sometimes i would hear a click and the sliding shaft would like slip and push in for a sec, then grip again...(this is when the motor was out and i was adjusting it)....
as far as the lock nut and the thicker nut/adjustment screw on the back, when i first got the ski, i was playing with/adjusting that thing when try to move/diagnose my trim problem, and now i think its not in the original position where it should be...
but i'll give the first thing a try in a little bit..
also, is the cover to the vts supposed to have a rubber deal/gasket like the breather box does?(to prevent water) cuz mine doesnt..it snaps in, but theres no gasket

Slipping isn't good, but you are doing it with the motor out. Just pull it out, VERY easy, take off the rubber boot on the back outside of the hull and pull it out and have a look. Hope that is your problem, cheap fix over the alternative!
Also, let me know if it does work, and how the worm screw looks, I will let you know how to help prevent it from sticking all the way down via thetrimfix solution for not over extending it.

When you get things back together, sounds like you are going to have to play with the rod/lock nut to get it adjusted correctly. Get it working then we can get to that.:thumbsup:
 
ok, well, tested the motor, outside of the housing, still connected and all...no good (motor works connected directly to a battery, in both directions) also tried new set of buttons...still no good...tested with lanyard on, both running, and not running...still nothing..
but i was able to take the worm screw out, push the slider assembly back out by pushing the nozzle up, then screwed worm gear all the way in, so its nice and snug exactly where i want the trim to be( a little higher than neutral, as i heard this will give you a little more top speed)..
so, in conclusion, im guessing the housing/module is shot, so i guess im gonna pass on it for now....
good to know that there's supposed to be a gasket on the cover..(i may have one from the other unit at home)...
also, i dont know if its just my ski, but when i did have full range of motion on the trim nozzle, it didnt look like there was a DRASTIC difference between full up or full down...(as far as inches)
 
Well that sucks, so ya it is definitely your module then. Ask Minnetonka4me what he sells his for.

No it isn't a huge difference, but a difference. The service manual tells you exactly what the degree of full up, and down is. Something around 8 degrees up, and 3 degrees down. If you don't care, just set it like you said you like it and leave it. I just like being able to play with it, and trim it right up and jump out of the water or wakes... so much fun! Least now you know how it works.
 
arite well, thanks for all the help....if i get some down time, i might mess with it again..so, from my 47.8mph, do you think i'll get at least 1.2mph from the adjustment to 49, or is that like chasing the wind?

NP! Like to help when I can since others have helped me out.

LOL...eee I don't know.... one way to find out :)

and only 47.8... my buddy has a 95spx with the 650 in it, no trim, and it does 55mph. It goes really good, keeps up with my 787 which kinda pisses me off, but my rave valves weren't working at the time etc... next season we will go again.
 
well i thought it was kinda strange too...plus it doesnt help when i hear Lou is doing 62-63 on his 96...grrrr..lol
the ski has perfect compression, new (used) mpem, plugs, plug wires, fresh oil, fresh/clean carbs, new motor mounts, and whatever else...
but i am using a handheld gps thats at least a few years old thats for a boat, and it has an mph conversion on it...
so, hoping that its off a lil, but i doubt it...

some other dude on here has an spx that does like 53...
but i read an earlier post with a guy with like a 92-93 sp with a whole buncha aftermarket parts, rideplate, exhaust, carbs, manual trim, etc..and cant get over 36.7, so that makes me happy...(doesn't say much, but it still does, lol)
 
LOL... from what I have read, Lou is doing that on his gsx, whatever reason (hull design etc.) they are faster than the x4 hull. Remember different years, different engine. Don't you have the 720? or is it still the 650?

My bros 97 spx is faster than mine, pisses me off since I picked out both skis and he just rides it lol... but still love the look of the 99 over the 97 even tho it is slower by a bit. His is around 58-59 for sure. Age and wear has a lot to do with it and his most definitely has less hours than mine on it.

You get what you get and go with it. Why you test ride them before you buy them used. I really wanted the 99 and there is not one for sale up here in Ontario CAN. I bought mine, before the guy ever posted it anywhere. They are very rare..so you take what you get I guess and enjoy it and screw the rest. Doesn't matter when you are ripping off waves :thumbsup:

But I'm looking to put a new impeller on it and wear ring (other thread). Doc is giving me some feed back.
 
yea, mine's a 717...but even people with the same year ski i hear of them hitting 53, 55, etc...and then even 95xp's, which are the same hull and motor, hitting 55,56....
so i think after thanksgiving im gonna bite the bullet and take the ski HOME (its been at my job on the water since ive owned it) and will replace the rusted/pitted driveshaft(had a nice condition used one, someone stole it right off the chair by my garage) wear ring, and carbon ring, and hopefully i"ll get another mph or so....
ps, i DID find that rubber gasket for the vts at home
 
so, put the trim in the all the way up position(manually)...my vts gauge does work cuz it was ALL the way up!...let me tell you...worst ride of my life! (well, also the funnest)....the ski was probably out of the water more than it was in...and i had the pos gps with me, and i actually LOST 1.3 mph...
so, should i move it completely back to neutral, or a lil bit higher than nuetral? what do you guys think?
 
Lol.... Least it is back together and you got to try the trim all the way up. It can be fun for waves messing around but not all the time. Why I really like the vts option. more fun with a push of your thumb.

I would set it just above half for prob your best top speed and running about.
